Simulation System Design of 3-D Panorama of Ship Motions in Wave

In this paper a 3-D panoramic simulation system of a ship is described which is developed with the MAXSCRTPT language and VC + + as programming tools on the platform of 3 Dsmax. The strip theory method is applied to the motion prediction of the mono-hull. The time history solutions of heave and pitch are obtained in the condition of head sea to provide the primary data on panoramic simulation. The simulation system has following functions: 1) digital simulation; 2 ) panoramic simulation; 3) environmental set-up; 4) render preview and output.     

Potential and benefits of AIS to Ships and Maritime Administrations

The Universal Automatic Identification System (AIS) provides a huge variety of potential applications and services which exceed the well known ship-to-ship data exchange. The purpose of this paper is to address the most important AIS services, in particular the AIS position report and the AIS safety-related and binary messages (“AIS telegrams”). The main issue is the impact of this new technology on the on-board use of AIS in collision avoidance (and its limitations) as well as the impact on shore-based services such as Vessel Traffic Service (VTS), port management and the need of an effective AIS network.     

Accessing the global seafaring labour market

As a global labour market exists for international shipping, a challenging issue facing this industry is to get access to reliable, accurate and timely information of seafarers’ demand and supply. Related to the deregulation environment and great variety in the availability and quality of relevant information, an enquiry into the global seafaring labour market is more complex than a national labour force survey. To cope with the challenge, a novel approach has been developed by the Seafarers International Research Centre (SIRC) at Cardiff University. Viewing capital (ship), labour (seafarers) and services (cargo or passengers) as interconnected and interwoven to each other, it collects and analyses crew lists from main ports world-wide, resulting in the creation of the first global seafarers database. The purpose of this paper is explain its methodological principles, and to illustrate its application potential. Taking the cruise sector as an example, research findings and methodological implications are highlighted.     

Prediction of Tyre-Road Friction with an Inverted-Boat Shaped Pressure Distribution

In this paper, a predictive model is formulated to describe the frictional forces between the tyre and road. The model is based on an inverted-boat normal pressure distribution. The determination of the input parameters is simplified by the suggested stationary point approach for calculation of the frictional coefficients, which are analytically obtained. The verification of the established model shows that the predicted values are in a good agreement with measured data. A sensitivity study of the shape factors demonstrates that it is necessary to take the unsymmetric normal pressure distribution proposed in this paper into consideration to accurately predict frictional forces.     

Estimation of origin-destination matrices from link traffic counts on congested networks

Conventional methods for estimating origin-destination (O-D) trip matrices from link traffic counts assume that route choice proportions are given constants. In a network with realistic congestion levels, this assumption does not hold. This paper shows how existing methods such as the generalized least squares technique can be integrated with an equilibrium traffic assignment in the form of a convex bilevel optimization problem. The presence of measurement errors and time variations in the observed link flows are explicitly considered. The feasibility of the model is always guaranteed without a requirement for estimating consistent link flows from counts. A solution algorithm is provided and numerical simulation experiments are implemented in investigating the model's properties. Some related problems concerning O-D matrix estimation are also discussed.     

中小航运企业发展现代物流的合理定位

目前我国的很多航运企业特别是大型航运企业都在积极地探索发展现代物流的道路.大型航运企业在发展现代综合物流领域已经取得了一些成功的经验,如中远成立了中远物流公司,并成功地进行物流运作,为我国航运业发展现代物流提供了典范.这些成功的典型范例,共同的一点就是在发展现代物流、切入物流市场之前,对企业进行了合理的定位.但是,我国的大部分航运企业都属于中小型企业,这些企业与大型航运企业的实际情况不一样,在发展过程中,不能照搬大型航运企业发展现代物流的模式.首先,也是最重要的,是要先对中小航运企业进行合理定位,分析和认清各航运企业在发展现代物流中的优势与不足,利用优势,克服不足,正确确立其在现代物流系统中的地位.
